Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

7.2K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

1.1K
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Endoscopic Procedures III: Video Capsule Endoscopy

1.5K
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Endoscopic Procedures I: Esophagogastroduodenoscopy

2.4K
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Urologic Endoscopic Procedure: Cystoscopic Examination

6.5K
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Endoscopic Procedures II: Colonoscopy

1.3K
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Summary
This summary is machine-generated.

Cumulative sum (Cusum) analysis, a personalized method, effectively tracks surgical trainee proficiency in percutaneous endoscopic gastrostomy (PEG) procedures. It identifies performance relapses missed by expert evaluations, enhancing training efficiency.

Area of Science:

  • Medical Education
  • Surgical Training
  • Endoscopic Procedures

Background:

  • Work hour restrictions limit surgical operative experience.
  • Need for personalized evaluation methods in surgical training.
  • Assessing cumulative sum (Cusum) for percutaneous endoscopic gastrostomy (PEG) proficiency.

Purpose of the Study:

  • To prospectively evaluate the utility of Cusum analysis for measuring surgical trainee proficiency in PEG procedures.
  • To compare Cusum analysis with expert evaluations for assessing proficiency and identifying performance lapses.

Main Methods:

  • Nine postgraduate year 1 surgery residents performed PEGs during a 1-month endoscopy rotation.
  • Procedure durations were recorded; task failure defined by attending takeover or duration >10 min.
  • Cusum parameters set with acceptable (5%) and unacceptable (15%) failure rates; expert evaluations used Likert scales.

Main Results:

  • Both Cusum and expert evaluations identified proficiency in most residents.
  • Cusum detected performance relapses in four residents, missed by expert evaluations.
  • Expert evaluations identified proficiency earlier for some residents.

Conclusions:

  • Cusum analysis is more sensitive than expert evaluation in detecting subproficient performance relapses.
  • Integrating Cusum with expert evaluations offers longitudinal feedback and optimizes operative experience distribution.
  • Cusum analysis enhances the efficiency and effectiveness of surgical training programs.
